The reason why the hot glue can be melted
Aug 05 , 2021
It may be a very complicated situation that the hot melt adhesive cannot be melted. It is the result of the mixing of the above reasons. There are many carbides in the glue furnace, which will cause inaccurate temperature control of the equipment for a long time. Even if the glue furnace is cleaned regularly later, but the temperature control of the equipment has long been damaged, it is difficult...

Application of hot melt adhesive on sanitary wipes
Aug 06 , 2021
Sanitary wipes have a sterilizing effect and can be used to clean and sterilize the surface of objects. Because the sterilization effect is required, the disinfected wet wipes contain alcohol, chlorine-containing disinfectants or preservatives; and alcohol is volatile, and the wet wipes with the cover can prevent the intrusion of microbial contamination from the opened package, and ensure that the...

How to identify hot melt adhesive quality
Aug 07 , 2021
There are many quality indicators of hot melt glue, requiring dedicated instruments and appropriate detection environments, in the absence of instrument equipment, is first seen from the appearance, there is no bubble. Secondly, the rubber is melted into a width of about 1 cm. Thick 0.2cm tape. After cooling, use it to extend the tape, and observe whether its stretch can achieve standards. Whether...

Application of hot melt adhesive machine in paper industry
Aug 09 , 2021
The hot melt adhesive machine is also widely used in the paper packaging industry. When using the hot melt adhesive machine in paper packaging, we need to pay attention to the temperature control. When the hot melt adhesive machine is heated to 1.5 ~ 1.7 times its melting point, it is applied to the first layer of di (single-sided corrugated board). The hot melt adhesive has the most appropriate s...

The bonding effect is good, and the surface treatment before gluing is indispensable
Aug 09 , 2021
Bonding generally refers to the bonding of two items through the action of hot-melt adhesive, and the bonding area of two items is called bonding surface. Before spraying glue by hot-melt adhesive machine, we need to treat the surface of bonded objects for better bonding. Any material will inevitably be stained with some stains in production and processing. Oil stains or some impurities, if the ma...

What is the reason for the insufficient amount of glue in the pump of the hot melt glue sprayer?
Aug 11 , 2021
The hot melt glue machine can work 24 hours a day, but what is its working principle? In fact, it is very simple, mainly by heating the hot-melt adhesive, and transporting the liquid hot-melt adhesive through power. The pump of the hot melt glue machine is the main power and the center of the operation of the hot melt glue machine. Sometimes when working, there will be insufficient pumps. This sit...

Precautions and treatment methods for surface hot melt adhesive bonding
Aug 11 , 2021
The key points of hot melt adhesive bonding knowledge and some basic processing methods. To activate the surface to be adhered, through chemical or physical methods, some polar groups are introduced into the surface layer, so that the low-energy surface becomes the high-energy surface, the inert surface becomes the active surface, and the difficult-to-stick surface becomes the easy-adhesive surfac...

The reason why the sealing machine is not strong
Aug 14 , 2021
1. Material selection of the box: The selection error mainly refers to the imperfect matching of the hot melt adhesive or the type of boxes that need to be bonded, and it is difficult to meet the process requirements of the material itself. 2. The temperature during compounding does not meet the requirements: The compounding temperature does not reach the melting point of the adhesive film or omen...
